-------------------------------------------------TITLE: Regular coffee beats decaf in protecting the brain from chronic stress, mouse study finds
Regular coffee consumption might do more than just wake you up; it appears to protect the brain against the damaging effects of chronic stress. A new study in mice found that drinking caffeinated coffee prevented stress-induced memory loss and mood deterioration, while decaffeinated coffee offered no such benefits. The findings, published in Neurobiology of Stress, suggest that caffeine is the primary ingredient responsible for coffee’s mood-protecting properties.
For years, researchers have tried to understand the relationship between dietary habits and mental health. Epidemiological evidence frequently points to coffee as a protective beverage. For example, a study covered by PsyPost in 2026 indicated that moderate coffee consumption is associated with a lower risk of mood and stress disorders. These population studies raised an interesting question about which specific parts of the complex beverage drive these benefits.
Scientific investigations have built a case for caffeine as the active ingredient. As an example, a 2011 study of women found that drinking regular caffeinated coffee was linked to a lower risk of depression, whereas decaffeinated coffee offered no such protection. Following this, a 2015 study in mice demonstrated that pure caffeine prevents the mood and memory problems normally triggered by long-term stress. Yet, a 2018 analysis showed that decaf coffee still contains nearly all of the same healthy antioxidants as regular coffee, leaving scientists wondering if other nutrients in the beverage also played a role.
To settle whether caffeine is truly the essential ingredient for stress resilience, Ângelo R. Tomé and Rodrigo A. Cunha of the University of Coimbra led a research team to directly compare the effects of regular and decaffeinated coffee. They focused on how these beverages affected mice exposed to chronic unpredictable stress.
Chronic unpredictable stress is a laboratory model used to mimic human depression and anxiety. By exposing animals to mild, changing stressors over a period of several weeks, scientists can observe the resulting emotional and cognitive decline. The research team also wanted to look closely at changes in the brain, specifically measuring long-term potentiation and brain-derived neurotrophic factor.
Long-term potentiation is a process where the connections between neurons strengthen, serving as a cellular foundation for learning and memory. This activity is heavily concentrated in the hippocampus, a brain region dedicated to forming memories. Brain-derived neurotrophic factor is a protein that acts like a fertilizer for the brain, helping neurons grow and survive. The researchers measured this protein in the frontal cortex, an area heavily involved in complex behaviors and emotional regulation.
The research team studied 24 adult mice, dividing them into four groups. One group drank water and experienced no stress. The other three groups underwent three weeks of chronic unpredictable stress. During this time, they experienced random daily stressors, such as damp bedding, a brief cold bath, or having their cage tilted. One of the stressed groups drank regular water, another drank a caffeinated coffee extract, and the final group drank a decaffeinated coffee extract.
The mice received their respective beverages during their active nighttime hours, starting a week before the stress protocol began and continuing throughout the experiment. The amount of coffee the mice voluntarily drank roughly translated to an adult human consuming about 350 milligrams of caffeine a day, or roughly two to three standard cups of coffee.
Following the three weeks of stress, the researchers put the mice through a series of behavioral tests. They used an open field arena to measure spontaneous movement and general anxiety. They also evaluated anxiety by seeing how much time the mice spent in the unprotected open arms of an elevated maze. To assess depressive-like behaviors, the team observed the mice in a forced swimming test, recording how quickly they gave up struggling and simply floated.
The team sprayed a sticky sugar solution on the mice for a splash test, measuring how quickly they cleaned themselves as a sign of motivation and self-care. They also tracked whether the mice lost their natural preference for drinking a sweet sugar water solution. A loss of this preference serves as an indicator of anhedonia, which is the inability to feel pleasure.
Finally, the researchers tested spatial memory. They watched whether the mice could recognize when a familiar object had been moved to a new location in a testing arena. They also tested whether the mice preferred to explore a newly opened arm of a maze they had previously navigated.
The results showed that chronic unpredictable stress took a heavy toll on the mice drinking plain water. Compared to the unstressed controls, these mice lost weight, displayed heightened anxiety, and showed a pronounced lack of self-care. They also exhibited severe anhedonia, drinking much less sugar water than usual. Their spatial memory suffered, as they struggled to notice moved objects or explore new areas of the maze.
However, the mice that drank caffeinated coffee weathered the stress remarkably well. Their behavioral patterns were nearly identical to the control mice that experienced no stress at all. The caffeinated coffee prevented the weight loss, the anxiety, the despair in the swimming test, and the loss of motivation for self-care. It also fully protected their spatial memory.
The decaffeinated coffee failed to provide these robust protections. The stressed mice drinking decaf exhibited almost all the same behavioral deficits as the stressed mice drinking water. They failed to recover their body weight, remained anxious in the open field and maze tests, and showed persistent memory issues. While the decaf group showed very slight improvements in a few areas, these small changes were not statistically meaningful.
The brain tissue analysis provided a biological explanation for the behavioral differences. In the stressed mice drinking water, the magnitude of long-term potentiation in the hippocampus dropped from a roughly 61 percent baseline increase down to just 25 percent, indicating a severe disruption in memory-forming capacity. The levels of brain-derived neurotrophic factor in their frontal cortex also plummeted.
Drinking caffeinated coffee completely prevented these neurological declines. The mice in this group maintained normal long-term potentiation and normal levels of the neurotrophic protein, keeping their brain networks highly functional despite the chronic stress. Just as with the behavioral tests, decaffeinated coffee offered no protection for the brain, leaving the mice with diminished synaptic plasticity and depleted protein levels.
The findings are in line with research covered by PsyPost in 2024, which found that caffeine protects rodents from stress-induced spatial memory deficits and hippocampal impairment. They also align with a study covered by PsyPost in 2025, which demonstrated that caffeine prevents stress-induced depressive-like behaviors and preserves neurochemical balance in mice.
However, the results are in tension with another study covered by PsyPost in 2024. That study found that non-caffeine compounds in coffee protected against stress-induced cognitive deficits. It is worth noting that the earlier research tested isolated coffee polyphenols during early development, rather than using whole decaffeinated coffee in adult mice exposed to chronic stress, which likely explains the differing outcomes.
As with all research, there are a few things to keep in mind. The study did not measure the exact circulating levels of caffeine or other specific compounds in the blood or tissues of the mice. Because the animals were housed in small groups during the fluid consumption phase to avoid the added stress of isolation, the researchers could not track the precise individual intake for every single mouse.
The testing was also performed on a mixed group of male and female mice without isolating sex as a variable. Past studies suggest there may be discrete differences in how coffee impacts mood in males compared to females, which this study design could not explore. Finally, translating behavioral and brain changes from mice to humans always requires caution, as human diets, stress factors, and brain chemistry are far more complex.
The study, “Regular intake of caffeinated but not decaffeinated coffee attenuates behavioral modifications in mice subject to chronic unpredictable stress,” was authored by Ângelo R. Tomé, Nuno J. Machado, Ana Paula Ardais, Ana Nunes, Henrique B. Silva, Manuella P. Kaster, Paula Agostinho, and Rodrigo A. Cunha.

-------------------------------------------------TITLE: Psilocybin reverses depressive behaviors and restores brain cell growth in stressed rats
Two doses of the psychedelic compound psilocybin can reverse signs of depression and anxiety in rats exposed to chronic stress. The substance appears to work by encouraging the growth of new brain cells and normalizing stress hormone levels. The research was published in Progress in Neuropsychopharmacology & Biological Psychiatry.
Major depressive disorder affects millions of people worldwide. Its core symptoms include persistent low mood, severe anxiety, and an inability to feel pleasure. The condition is associated with a loss of synaptic connections in areas of the brain responsible for regulating emotions. Current medications, such as selective serotonin reuptake inhibitors, do not work for every patient and often take weeks to show any benefit.
Researchers are increasingly looking toward psychedelic substances as alternative therapies. Psilocybin is the active compound found in “magic mushrooms” and has shown promise in treating depression in human trials. Scientists are trying to figure out exactly how the chemical alters the brain to produce these lasting benefits.
Prolonged psychological stress can physically alter the brain by reducing the formation of new connections between neurons. Chronic stress also hyperactivates the body’s natural response to threats, leading to an overproduction of stress hormones from the adrenal glands. Over time, this hormonal flood impairs a region of the brain called the hippocampus, which handles emotion and memory.
Agnieszka Bysiek and Krystyna Gołembiowska, researchers at the Polish Academy of Sciences, led an investigation into how psilocybin might repair this stress-induced damage. They worked alongside colleagues from the Medical University of Warsaw. The team designed an experiment to track behavioral changes and biological markers of brain healing.
The researchers conducted a small study using adult male rats. They divided the animals into groups and exposed one group to a routine of unpredictable mild stressors over several weeks. These stressors included temporary food or water deprivation, tilted cages, and strobe lights.
The goal was to induce a state similar to human depression, particularly a loss of pleasure known as anhedonia. To measure this loss of pleasure, the researchers tracked how much sweetened water the rats chose to drink. The stressed animals drank substantially less sugar water than the unstressed control group.
The researchers then administered two low doses of psilocybin to the animals, spaced one week apart. Following the treatment, the stressed rats resumed drinking the sweetened water at normal levels. This behavioral shift indicated that the psychedelic compound had effectively reversed their anhedonia.
Next, the team evaluated anxiety-like behavior using specialized laboratory enclosures. One test used a box divided into a brightly lit area and a dark compartment, while another used an elevated maze with both open and enclosed walkways. Stressed rats naturally avoided the light and open spaces, seeking the safety of the dark or enclosed areas.
Following the psilocybin treatment, these stressed animals spent more time exploring the bright and open sections of the enclosures. This change in movement patterns suggested a marked reduction in anxiety. The researchers also monitored the animals for head shakes, a common physical reaction in rodents that indicates a drug is causing hallucinatory effects. Both the stressed and non-stressed rats exhibited these shakes after receiving psilocybin.
The researchers also observed the rats in a cylinder filled with water to measure behavioral despair. Rats that simply float without trying to escape are considered to be exhibiting a depressive-like lack of motivation. The psilocybin treatment reduced this immobility, causing the stressed rats to actively swim and climb the walls of the cylinder.
To ensure the animals were not simply experiencing general hyperactivity from the drug, the team placed them in a large, circular open arena. The stressed rats given psilocybin walked around and explored the center of the arena more than untreated stressed rats. The psilocybin actually reduced walking and exploration in the non-stressed control rats.
The team then examined the brains of the animals to understand the biological changes driving these behavioral shifts. They used chemical markers to identify newly formed cells in the hippocampus. The chronic stress had suppressed the creation of new neurons in this region.
The psilocybin injections reversed this cellular deficit. The drug promoted the proliferation, maturation, and survival of new brain cells in the stressed rats. This finding supports the idea that psychedelics help the brain rewire itself by physically growing new cellular architecture.
The researchers also analyzed the genetic expression of a molecule called brain-derived neurotrophic factor. This protein helps neurons grow and form new synaptic connections. They found that psilocybin boosted the genetic instructions for producing this growth protein in both the hippocampus and the prefrontal cortex.
This boost in genetic signaling was apparent just two hours after the first dose. The elevated signals persisted for two weeks after the second dose in the stressed animals. Finally, the researchers measured corticosterone, a major stress hormone in rodents.
The chronically stressed rats had elevated levels of this hormone in their blood. A single dose of psilocybin brought these hormone levels back down to normal within two hours. Fourteen days after the second dose, the stressed animals still maintained lower, healthier hormone levels.
The study comes with a few limitations that provide context for the results. Animal models of depression do not perfectly map onto complex human psychological conditions. The testing environment also heavily influenced the behavior of the rodents, as the animals reacted differently depending on whether they were in an open arena or an enclosed box.
The biological measurements also require a measured interpretation. The research team measured the messenger RNA for the brain growth protein rather than the actual protein itself. Messenger RNA acts as a temporary set of genetic instructions translated from DNA. An increase in these instructions does not always guarantee a proportional increase in the final functional protein product within the brain’s cells.
Future research will need to measure the actual protein levels in the brain to confirm that the biological building blocks were fully assembled. Scientists also plan to investigate how long these cellular changes last after the psychedelic compound leaves the body.
The research provides a foundation for understanding how psychedelic therapies might repair the physical toll of chronic stress. The study, “Psilocybin restores behavioral and neuroplastic deficits induced by chronic stress in rats,” was authored by Agnieszka Bysiek, Izabela Szpręgiel, Adam Wojtas, Marzena Maćkowiak, Agnieszka Wawrzczak-Bargieła, Monika Leśkiewicz, Ewa Trojan, Katarzyna Kamińska, Weronika Kumorek, Wiktor Bilecki, and Krystyna Gołembiowska.
